"He" is not arguing with the fact that it seems possible to achieve somewhat
better scalability using asynchronous calls. "He" just doesn't like the
fact that this would mean writing the processing algorithm in a specific way
to suite the needs of asynchronicity. And "he" generally believes in
separation of concerns, so "he" doesn't want his processing algorithm to
know that it is used from the networked environment.
